01_​Hitlist_​Filter

Filter an HTS hitlist

This workflow demonstrates the initial steps of a high-throughput screening hitlist triaging workflow: removing molecules that may have interfered with the assay (using the PAINS filters) or that have undesirable physicochemical properties (using the REOS filters).
